QUICKLY!!!<br> I need the answer to this, please
Yuri [45]

8/(1/6) = (8/1)/(1/6) = (8/1) * (6/1) = 48/1 = 48

Patel found the quotient incorrectly since he got 1/48.

To check the division, he needed to multiply 48 by 1/6 and get 8.

Instead, he multiplied 1/48 by 6, so the multiplication done as a check is also incorrect.

Please help with this area
agasfer [191]

Answer:

L = 7 W= 12

Step-by-step explanation:

Ok so we already know that a rectangle is not even so the numbers will have to be 2 diff numbers.

The length is 5 feet less then width

w*l=  84

1* 84         2* 41        3*28    4*21    6*14    7*12

84-1           41-2        28-3     21-4     14-6   12-7

83              39           25          19        8         5

So,

your equation would be l*w = 7*12

4x-6y-3x-6y(4)

4x-6y-3x-24y

x-30y
